Yes, I fully intend to call them in the morning, not only because of this, but because the hinge pin that the locking clamp bolt threads into seems to be wrong. When I move the pin so that the clamp bolt fits through the slot on the front portion of the frame, the pin protrudes out the side to the point it prevents the the plates from coming together. If I center the pin so that doesn't happen, the clamp bolt misaligns with the slot. I'm guessing that the pin was just mismachined.

It's odd that the video I found on YouTube for assembling this trike has the Tri-Fecta name in the same fashion, instead of Port-O-Trike also. As it is, it looks to me that the Worksman and Tri-Fecta both come from the same place, regardless of what Walmart says.
